I pretty much agree with that. The first rinse is quick. Then as washing is the last step I clean up the darkroom during the wait time. I also have a 4 year old who likes to hang out in the darkroom as I develop the film. He really likes to shake the tank and see what color the solutions change to when they are poured out of tank. Also I do a final rinse in Photo flow so I guess that really counts as 4 changes of water.
